Real estate development

Real estate development, or property development, is a multifaceted business process, encompassing activities that range from the renovation and re-lease of existing buildings to the purchase of raw land and the sale of developed land or parcels to others. Real estate developers are the people and companies who coordinate all of these activities, converting ideas from paper to real property. Real estate development is different from construction, although many developers also manage the construction process.

Developers buy land, finance real estate deals, build or have builders build projects, create, imagine, control and orchestrate the process of development from the beginning to end. Developers usually take the greatest risk in the creation or renovation of real estate—and receive the greatest rewards. Typically, developers purchase a tract of land, determine the marketing of the property, develop the building program and design, obtain the necessary public approval and financing, build the structures, and rent out, manage, and ultimately sell it.
Sometimes property developers will only undertake part of the process. For example, some developers source a property get the plans and permits approved before on selling the property with the plans and permits to a builder at a premium price. Alternatively, a developer that is also a builder may purchase a property with the plans and permits in place so that they do not have the risk of failing to obtain planning approval and can start construction on the development immediately.
Developers work with many different counterparts along each step of this process, including architects, city planners, engineers, surveyors, inspectors, contractors, leasing agents and more. In the Town and Country Planning context in the United Kingdom, 'development' is defined in the Town and Country Planning Act 1990 s55.

Photographic developer

In the processing of photographic films, plates or papers, the photographic developer (or just developer) is one or more chemicals that convert the latent image to a visible image. Developing agents achieve this conversion by reducing the silver halides, which are pale-colored, into silver metal, which is black (when a fine particle). The conversion occurs within the gelatine matrix. The special feature of photography is that the developer only acts on those particles of silver halides that have been exposed to light. Generally, the longer a developer is allowed to work, the darker the image.

Chemical composition of developers

For black-and-white photography, the developer typically consists of a mixture of chemical compounds prepared as an aqueous solution. Three main components of this mixture are:

Perlé

Perlé was a commune in the canton of Redange until 1 January 1979, when it was merged with the communes of Arsdorf, Bigonville, and Folschette to form the new commune of Rambrouch. The law creating Rambrouch was passed on 27 July 1978.

Perl

Though Perl is not officially an acronym, there are various backronyms in use, the most well-known being "Practical Extraction and Reporting Language". Perl was originally developed by Larry Wall in 1987 as a general-purpose Unixscripting language to make report processing easier. Since then, it has undergone many changes and revisions. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another.
